Hi there,
I am also thinking of buying a polytunnel. Maybe 12 x 20ft. However I’m in Cambridgeshire and the temperature last week was 34 degrees in the shade. I’m worried about ‘cooking’ any delicate plants in the obviously hotter temperature in a polytunnel. Is a door each end really enough for this temperature? This would be on an allotment and I can’t always get there to water/open/shut doors. Any other suggestions to keep temp down in extreme conditions? Thanks for help
